Poncho The Buffalo Long Sleeve Shirt

Poncho’s Buffalo is a performance flannel long sleeve that leans more technical than a standard cotton shirt. It’s a medium-weight flannel, with stretch and a soft hand, and Poncho states the fabric wicks moisture and dries fast. That mix suits cool mornings, travel days, and fishing when you want a flannel feel without staying damp after a little spray or sweat.

Poncho adds fishing-specific details: a built-in lens cloth, a sunglasses holder, and a hidden zippered pocket.

The main change across our options is fit. Regular runs roomier. Slim is trimmer through the torso and arms.
